Connect the earth lead to “-”, tighten clockwise; Connect the electrode lead to “+”, tighten clockwise; Each machine is equipped with a power cable should be based on the input voltage welding power cable connected to the appropriate position, not to pick the wrong voltage; With the corresponding input power supply terminal or socket good contact and prevent oxidation;... - Page 10 3.2.3 One of the most common types of arc welding is manual metal arc welding (MMA) or stick welding. Welding An electric current is used to strike an arc between the base material and a consumable electrode rod or ‘stick’. The electrode rod is made of a material that is compatible with the base material being welded and is covered with a flux that gives off gaseous vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination.
